CMH Design & Consultancy Services offers expert guidance in compiling and managing test programmes for interior building products, including drywall partitions, demountable systems, fire doors, ceilings, flooring, and cladding panels. Whether you’re developing new systems, modifying existing designs, or responding to project-specific or regulatory demands, we work closely with you to determine the most effective testing route—ensuring full compliance and maximising your return on investment.
All acoustic and structural testing is carried out in UKAS-accredited laboratories using experienced installation teams. We test to standards such as BS EN ISO 10140 for acoustic performance and BS 5234 for structural robustness and durability of partitions. Where required, we also arrange on-site acoustic Pre-Completion Testing to demonstrate compliance with Building Regulations Approved Document E, as well as BB93 performance criteria for educational environments.
